The Gatchaman are a group of superhero fighters rumored to exist in urban legends, blurry pictures and second-hand hearsay. Teenager Hajime Ichinose has heard the gossip, but she never imagined her love of stationery would make her a candidate to be a Gatchaman… as their suits are empowered by cosmic notebooks! Hajime teams up with the stern Sugane Tachibana, aloof Jou Hibiki and other beacons of justice - but the Gatchaman are not this world’s only heroes, as Galax, a social media app, lets anyone use their unique skills to assist in a crisis! Strangers and newfound friends must now band together to stop Berg Katze, a mysterious alien who threatens the world with death and destruction.
